I saw the interview too WP. I guess being so far away, here in Victoria, we never really get to see how good some of the players from other states are and you never get to know their personality or anything much about them.
From the interviews I saw of him over the weekend, you can see why he was so successful and why he became the great player he was, because he obviously knuckled down and took on the challenges that Mick Malthouse set for him. The great thing for him was that Malthouse could see what he was capable of and got that out of him and possibly more.
Glen seems content that he got the best out of himself and leaves the game without regret of what might have been.
Good luck to him.
